hello,
can an expert give me a value on this unexploded set of 12 postcards with views of puerto rico. they seem to be from the 40's and lithographed. the front bottom has this printed:

GARITA DEL DIABLO, SAN JUAN. P. R. COPYRIGHT MCMXL BY CURT TEICH & CO., INC. CHICAGO, U.S.A.

thank you.

regards,
beachwarmer

the back view:

Hi

As a set this packet generally sells for $15-30 USD retail

Each card by itself would sell in the $3 to 4.50 range retail

If I had the set I would separate the cards, List them at $4.50 Fixed price each and let them sell as buyers find them.

Wholesale price is 25% to 30% of the retail price.

These cards are not rare. They are also indestructible, hence most have survive thru the years
